High Capacity One Way Backstop Bearing With Keyway And Clutch Design
✔️ Single pack 40x80x18mm steel freewheel backstop bearing with keyed shaft slot

This one way backstop bearing locks rotation in one direction while allowing free spin in reverse. You will find these units hanging out on conveyor rollers, mixers, and heavy duty winch systems where reverse movement needs to stop instantly. The solid build handles serious torque without slipping, making it a reliable swap for worn out clutch assemblies.

✅ Overall size measures forty by eighty by eighteen millimeters for standard mounting fits
✅ Machined keyway aligns perfectly with drive shafts for secure torque transfer
✅ Internal ramp plate mechanism provides instant directional locking under load
✅ High carbon bearing steel construction resists wear from constant friction cycles

💡 Why install a ratcheting backstop clutch on heavy industrial motor drives? These directional locking units are handy for killing reverse motion fast without running extra wires or control boxes. They pull weight reliably and kick in smoothly under serious shop floor loads. - internal cam tracks grip the outer race firmly during negative rotation phases - hardened steel ramps distribute backward shock loads evenly across the full face width - self adjusting clearance maintains steady holding force through thousands of cycles
